Abstract
Power capacitor plays an important role in the aspects of improving power factor
voltage quality
transmission capacity of power line and stability etc. and
at the same time
is an important equipment of HV DC converter station
therefore the test of power capacitor is of particularly important. In the study of power capacitor test
bridge type harmonic current injection is a kind of method with most attention. In this paper
programmable harmonic power monitoring system based on PLC and touch screen is designed for monitoring harmonic power in the bridge type whole harmonic current injection method. The experiment shows that the system operation is simple
practical and can achieve data monitoring effectively.
